Abstract: The effective bottom Yukawa couplings are analyzed for the minimalsupersymmetric extension of the Standard Model at two-loop accuracy withinSUSY-QCD. They include the resummation of the dominant corrections for largevalues of tgbeta. In particular the two-loop SUSY-QCD corrections to theleading SUSY-QCD and top-induced SUSY-electroweak contributions are addressed.The residual theoretical uncertainties range at the per-cent level.
